About J.M. Davis
John Monroe Davis (1887-1973) assembled what is often called the world’s largest privately owned gun collection, now preserved at the J.M. Davis Arms and Historical Museum in Claremore, Oklahoma. Davis received his first gun at age seven, bought Claremore’s Mason Hotel in 1917, and by 1929 was displaying firearms on its walls, which drew travelers on the highway that became Route 66.
In 1965 Davis transferred the collection to the J.M. Davis Memorial Foundation, which agreed to give it to the State of Oklahoma; the state legislature created the J.M. Davis Memorial Commission, and the foundation holds a 99-year lease with the state for $1. The museum, which fills a full city block, opened to the public on June 27, 1969, Davis’s 82nd birthday. Today it holds more than 12,000 firearms along with thousands of other artifacts, from early muzzleloaders to outlaw and lawman guns, and it remains one of the most important firearms history destinations in the United States. Davis died on February 7, 1973.
